Abstract
Anesthetics are used to reduce stress in fishes during handling and transfer. However, deep anesthesia of seawater‐adapted mummichogs (Fundulus heteroclitus) results in a time‐related increase in plasma cortisol, indicating a primary (neuroendocrine) stress response. Groups of seven fish were bled within 1 to 12 min of exposure to the anesthetic MS‐222. Plasma cortisol rose more rapidly in fish removed from the MS‐222 solution immediately after 1 min and held between wet paper towels than in fish that remained immersed. The difference between methods was significant (P < 0.001) with variation restricted to the later sampling periods. Differences were not significant in fish sampled immediately after 1 min (P > 0.05).
